VAPORIZER Herbert E. Pritchard, New Orleans, La.

ApplicationMay 20', 1946,' SerialA No. 67130865 filaims.. 1

The present invention relates to a vapQr-lZer. More particularly, itrelates to a vaporizer for inhalant material that usually is providedin.a.j.elly or salve-like form, which; vaporizer may conveniently becarried in the pocket, and-which has an igniter and flame supportingmeans readily operable so that the medicine may be vaporized` wheneverit is needed.

This invention is an improvement upon copending application Serial No.615,362, ledSeptember 10, 1945, by this inventor.

It is an object of thel present invention to provide a vaporizer of thistype inK which the height of the flame may be easily adjusted. Aparticular object is to provide for the flame adjustment by anadjustable connection between a casing and a fuel cartridge barrel,providing for adjustment.

of a wick.

A further object ofI the invention.- isto provide ondary air to beavailable for the iiameV atthewick.

Further objects include the provisionof a. device of this kind that maybe easily and inexpensively fabricated, and yet which will be durableand, de.- pendable in use.

Other objects will appear from the description to follow and from thedrawings, inwhich:

Fig. 1 is an elevation of the device;

Fig. 2 is an elevation from the rightv side of Fig. 1;

Fig. 3 is a transverse section,taken on. the line 3-3 of Fig, 2; `andFig. 4 is an extended View of the severalparts, showing the manner inYwhich they intert.

The device consists of an outer casing C that is generally tubular. Ithas a lower cylindrical part I with threads I I; and it has an upperflaring part l2 terminating in a, sleeve-like portion I'S. The upperpart is provided with a suitable number of openings I4 which provide airto the wick, and also provide escape for combustion gases. The top partof Vthe lower section lil-is `also provided with additionall openings I5to; provide air to the wick.

Immediately above the openings I5 and at the junction of the lower andupper sections I0 and I2 of the casing C, there is a ame baffle I8, inthe form of a flanged disc that is permanently united to the casing C atthe point indicated. The baffle I8 has a central opening I9. Thiscentral opening I9 receives the wick, as will appear.

The lower part ID of the casing C is adopted to receive an innercartridge 22 that is generally tubular. The cartridge 22 has threads '23that are designed to. inter-.operate with. the threads I,I.v on thelowercasing section Ill. Bythis means, the cartridge- 22 may be adjustablylocated at agproper point within the lower. section, I0.

The Acartridge 22. hasasomewhat taperingupperl end wall 24.,Vwhich.providesa center opening. 2,5,.to. receive and hold a Wick 2,6..Thiswick. extendsv down into thecartridge 22 and is.. embedded. in-4suitableliquidfuel holdingmeansll, such as 'cot-1. ton.

Whenv the cartridge 22.is insertedjntothe casing l0. and the threads.-engaged, a. closure cap 2S!4 may be irictionally slid over theprojectingpart, of the cartridge '22;` and sealed, tightly therewith.Preferably, the cap 29, has a band. of; insulatingI material, such4asplastic, around it. This furnishes a, mean to hold. the vaporizerevenl should, it b ecome hot.

The lower section Ill of the casing- C; at.. oneside supports a flintsleeve 3 2. Thisr sleeve, in turn, supports an abrasive wheel 3,3 at itstop end. It. also contains a flint 'thatis urgedupwardly by a coilspring l under controlofaplunger 3,6,.withj a suitable handle thereon.In order to permitconf.

venient replacement of 1iin ts, va n4 opening 3 1'. isV

provided in the side of thesleeve 32,'. When the plunger 36 is drawndownwardlmianew flint may` be inserted intoplace.

The wheel 33 projects .through anopening 3!! in the side of the uppersection and' is arranged. so that, when the wheelis turned; Vitv willdeliver a spark to the wick.

The sleeve I3'- at the'top' ofthecasing' Q supports a pan 42 thatpreferably is. permanently attached into the casingalthoughrit may be.re,-

movable if desired; The pan Miisanged at 4 3:

to limit its downward movement in thesleevelike topv sectionA lf3 ofthecasing, Itis adapted also to receive a closure capV 44' thatjtjs overjit above the flange; 43.

In operation, the pani 4-2 will containa vapore* izahle medicine. Thismaybe in the form Qf a jelly or it may be supplied as a disereadilyin'-sertable into the pan 4:2: for being kept'in the pocket, the cap 44"will be disposed over the top of the pan 42, so that the material cannotescape therefrom. When it is desired to inhale fumes of the medicant,the cap 44 is removed. Then the wheel 33, which projects convenientlyoutside of the casing, is rotated to deliver a spark to the projectingpart of the wick 26, which is, of course, supplied with suitable liquidfuel from the cartridge 22. This fuel ignites and thereby provides aflame on the bottom of the pan' 42 which causes the jelly or Forstorage, such'. .as i

the like to vaporize and supply fumes that may be inhaled.

The primary air for the wick is supplied through the openings I5. Theseopenings can deliver fair to the wick owing to the fact that the -centerpart of the top wall of the cartridge 22 projects upwardly, as appearsclearly in Fig. 3. Secondary air is provided through the openings I4,these openings also providing for the escape of the gases of combustionfrom the wick itself.

When it is desired to refuel the cartridge, it is necessary only to pullthe lower cap 29 off of the cartridge and pour in the necessary amountof fuel.

It will also be understood that the refueling of the medicine pan 42 isequally easy. This may be done by filling the pan with medicine in anywell known way, or the medicine may be supplied in cartridges that .fitreadily into the pan 4Z.

One of the features of the present invention is the flame adjustment. Ithas been found that the amount of flame must be controllable in order toavoid the possibility, for example, of ignitingr the fumes of themedicine where the medicine consists of a combustible material. Also, itis desirable not to have excess flame because the same is awkward tohandle :and is apt to burn the user. And too much flame produces excessheat- `ing of the device itself.

On the other hand, too little flame will not provide adequatevaporization or will operate too slowly.

The proper flame can be obtained in the present device by adjusting theamount of projection of the wick 25 through the port I9 of the flamebaille plate IE. This adjustment is easily obtained by turning thecartridge 22 (or merely the lower cap 29), so that threads 23 in thecartridge nteroperating with the threads I I on the casing, move thewick upwardly or downwardly to dispose the wick 26 properly through theopening IS. As the wick is raised, the size of the flame is increased.

By the foregoing arrangement, which is obviously both inexpensive anddurable, a proper flame may be provided. The danger of igniting thefumes is eliminated, and yet the vaporization may be obtained at desiredspeed.

It will be seen that this device accomplishes the objects set forth forit, and affords a con-l venient and satisfactory pocket type ofvaporizer.
